DANIEL J. REARDON, OF WESTERLY, RHODE ISLAND.

RATCH ET-PAWL.

SPECIFICATION forming part of Letters Patent No. 493,944, dated March21, 1893.

Application filed November 25, 1892. Serial No. 453,031. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL J. REARDON, of Westerly, in the county ofWashington and State of Rhode Island, have invented certain new anduseful Improvements in Ratchet- Pawls; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention has reference to improvements in ratchet pawls or catcheswhich are particularly adapted for use on the ring-railcontrolling-ratchets of spinning-machines.

The object of the invention is to produce a ratchet-pawl which shall bemore positive in its action when operated by an independent arm thanthose as heretofore constructed.

The invention consists in forming a pawl having an enlarged-tooth, acounterbalanceshoulder, and a peculiar frame adapted to surround the endof the operating-rod which is free to move therein to an extentdependent on the internal size and shape of the frame.

Figure 1 represents-a view of the improved ratchet-pawl. Fig. 2:represents a view of the same when used in a spinning-frame, theringrail controlling-ratchet and its immediate cooperating parts beingshown.

Similar numbers of reference designate corresponding parts throughout.

In carrying my invention into effect I form a ratchet-pawl having thedownwardly extending tooth 5, the upper portion of which is perforatedas at 6 to receivea pivot on which the pawl may turn; extending from theupper outward curve of the tooth 5 is the counterbalancing shoulder 7,which is connected by the upwardly-extending member 8 with the cross-bar9, the opposite end of which is connected by the bar 10 with the upperportion of the pawl -tooth. The counterbalancingshoulder 7 is furnishedwith the internalsocket 11, from which the edge forming the upperportion of the pawl-tooth curves sidewise and upward, forming a surfaceon which the bent finger which operates the pawl rides when shifting thepawl.

When used in a spinning-machine and the arm 12 is operated to engage thepawl-tooth with the ratchet, the pawl is positively held in the positionshown in Fig. 2 of the drawings, from which no accidental blow willrelease the pawl, thus preventing irregular building of the yarn on thebobbins. The improved pawl is, however, useful wherever the operation ofthe same is caused by an independent-arm which would be apt to slip 06from an external shoulder.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A ratchet-pawl, consisting of the engagingtooth 5 thebase of which is perforated at one side as at 6, thecounterbalancing-shoulder 7 extending from the base of the tooth, themember 8 and the bars 9 and 10 surrounding an opening the lower end ofwhich forms a socket 11 extendinginto the counterbalancing-shoulder, asdescribed.
